The main objects thisinventionareto provide means forgiving a clearvvisionunder' adverse atmospheric conditions, "for drivers of vehicles, railway engines, motor ,j boatsand thelike. I
3 Ividing meansfor enabling-the engineer. to see i the road ahead an d esp'ecially the signals in stormy weather and in sleet and snow. Herein tofore :it has been necessary in some cases to use peep'f holes which afford a clear vision, butfexpos'e the engineer to they weather. In my'invention I provide a disc which is rotated-at very "high speed. In tests under actual service conditions it been shown 'that thepraingisteam, sleetjor sriowcannot t cloud the vision throughthe dlscas long as;
the disc' is fejv'olving. I The disc may be used directly fora window, or may be placed over ro the windows already provided; In a railway-V engine, the glass disc'is rotatably mounted in a frame which is hinged to the franie of the; V cab window so that the device can be swung.
', out of the way when desired as in cleaning the window."
Other objects and advantages-are to pro-f vide'a clear vision, rotating disc which is mounted at'the margins so that the center of V the disc is unobstructed; to providesuch-af 3o device inwliich'the parts can be made at low cost; to provide frictionless bearings, v .mea-ns ofpocketsinthe ball retaineriring 15.

The felt strips may be cemented,
either to the frame or to the window glass, and serve to keep the moisture and dirt out from underthe disc 1. The swinging edge of the frame is clamped in place-by means of thetoe bolts 18, which engage the edge of the frame and extend through the frame 41 of the window. The boltsjareremovably secured by p the nuts 19 which are threaded onto the bolts 0n the inner side ofthe window. 1
For driving the disc, a groove" 20 is vided in the periphery of the sash ring, the groove having suitable blades or ratchet teeth 21 icontained therein 1 for catching the air.
' The: air pressure nozzle22 is fixedly mounted on. the window frame-'4} by; means of. the clamp 23, and the'out'erf end of the nozzle 1s flattened as shownin section in Fig. 4' so as to cover a. segmental portion of the groove 20. The' edge of the ring 2 and the lower filler 17 are vcut away as shownto allow them to swing out awayfrom the nozzle.
.The nozzle is provided with asuitable. valve 25 Whichis preferably located within the cab where it is convenient for the engineer forcontrolling the speed of the disc and a connection is made by suitable pipes to the compressedair reservoirs of the engine. By
1 locating the end of the nozzleon the under side of the disc, the weight of thedisc is par tiallyfcarried by the pressure of the-air, and: the disc rotates with very little friction. i For starting the moisture to move away from the center of t'he'disc, the glass strips 28 may be used. These strips are secured to the surface .of the disc at the center by transparent cement center of the disc, which is alsothe center of thevision, is leftunobstructed. The frame partsxcan be made almost entirely by stamp= ing processes; the bearings andljoints are well protected; and the'outer surface of the de-' vice is smooth and does not offer anyz-obstructi onsforcollecting moisture and dirt. 1 Having-thus "described my invention, I
